Any thoughts on this? I'm still in the testing stages....but, here goes. I've had very loose/watery stools since February, pain just under the left breast and travels down the abdomen, acid reflux, very unusual smelling gas (if that's possible!), burping and bloating. I've had 4 blood tests, 2 bowel tests, 1 colonoscopy, 1 Abdominal CT scan with dyes and I'm scheduled for a sygmoidoscopy/biopsy in 5 days. Is the pain on the left side typical of IBS? Food chooses do NOT affect the bowels. High fiber, HIgh fat, caffiene, yummy muffins, milk products, spicy foods or bland oatmeal...no changes to the stools. What are your thoughts?
